During engine priming he noticed you had to rotate the crank to get any oiling. When the oil started to flow, it was like a waterfall out of the rocker shaft which really seemed excessive! Is this common? Should I have used oil restrictors? I have a high volume oil pump, same one most people use on ~450-500hp engine build.

Otherwise check the end plugs. 383B, 9.8:1, Lunati 60302(220/226@0.050 262/268Dur, 0.475"/0.494", Stealth heads, Performer manifold, QF SS-750-AN carb, 3.31Diff, A833 4-speed manual.
